Differential diagnosis includes non-specific interstitial pneumonia, pulmonary Langerhans cell histiocytosis, respiratory bronchiolitis-associated interstitial lung disease, and hypersensitivity pneumonia. DIP is primarily treated by quitting smoking, but it may not be enough in all cases. In moderate to severe cases, corticosteroids are used.
Micrograph showing a Masson body (off center left/bottom of the image – pale circular and paucicellular), as may be seen in cryptogenic organizing pneumonia. The Masson body plugs the airway. The artery associated with the obliterated airway is also seen (far left of the image). H&E stain. Specialty: Pulmonology Symptoms
Pulmonary veno-occlusive disease (PVOD) is a rare form of pulmonary hypertension caused by progressive blockage of the small veins in the lungs. [2] The blockage leads to high blood pressures in the arteries of the lungs, which, in turn, leads to heart failure .
It is diagnosed around the time of birth or in the first 6 months of life, occurring more often in boys than girls. CLE affects the upper lung lobes more than the lower lobes, and the left lung more often than the right lung. [38] CLE is defined as the hyperinflation of one or more lobes of the lung due to the partial obstruction of the ...
Mycobacterium avium complex (MAC) is the most common cause of NTM lung disease in most countries, including the United States. [6] Classically, MAC infection results in either upper lobe cavities in male smokers with COPD or bronchiectasis in thin, older women; however, it is possible to have both cavities and bronchiectasis in the same patient ...
Lower respiratory infectious disease is the fifth-leading cause of death and the combined leading infectious cause of death, being responsible for 2.74 million deaths worldwide. [27] This is generally similar to estimates in the 2010 Global Burden of Disease study. [28]

Necrotizing pneumonia (NP), also known as cavitary pneumonia or cavitatory necrosis, is a rare but severe complication of lung parenchymal infection. [1] [2] [3] In necrotizing pneumonia, there is a substantial liquefaction following death of the lung tissue, which may lead to gangrene formation in the lung.
